In the process of trying to install 4.4.4 on my galaxyTab 10.1, I've installed TWRP 188.8.131.52.
At this point when in recovery mode I need to select the Zip to install, but none of the previously downloaded zip files are visible to TWRP. Neither under the install command nor in the file manager.
I had backed up, removed caches et al. When rebooting in normal operation mode, those files are browsable. Permissions are set to 777.
So I don't understand where the hang-up is?
